Application filed February 24, 1915. Serial No. 10,201.

To all whom it may concern Be it known that I, FRITZ KonLLEn, a subject of the King of Prussia, residing at C0- logne, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in Bayonets, of which the following is a specification;

This invention relates to bayonets which are fixed on the forward end of guns by means of a slot provided in the handle of the bayonet and adapted to receive a projecting shoulder of T-like, or cross-like section, provided on the gun. 1

To lock the shoulder of the gun in the slot of the bayonet, it is usual to provide a spring-pressed sliding bolt within the handle of the bayonet which bolt projects into the slot and is adapted to engage a suitable stop on the shoulder of the gun after the To enable the bayonet to be detached from the gun the spring-pressed locking bolt is retracted by hand whereupon thebayonet can be removed from the gun. When detached from the gun it is usual to carry the bayonet in a waist belt. In the detached condition the open slot in the handle of the bayonet is liable to frequently become clogged with sand, loam, snow, or the like, since the soldier has often to couch on theearth and to stay in trenches. 'If, then, the order is given to fix the bayonet the soldier will have to clear the slot of the bayonet before he is able to fix same on the gun. Valuable time is lost thereby; and in many cases he will be unable to fix the bayonet securely.

It is the object of the present inventionto provide means by which this default is effectively met. The means consisting of a stopping piece which is inserted into the slot of the dismounted bayonet and fills same up or closes it so that no foreign bodies can enter the slot during the time the bayonet is carried in the belt.

The novel means for stopping the slot of the bayonet is illustrated in the drawings in which Figure 1 shows the handle of a bayonet in side View, theblade'of the bayonet being broken away. Fig. 2 is an edge view of the bayonet handle shown in Fig. 1.- Fig. 3 illustrates a cross section along the line 33 in Fig. 1; Fig. 4: is a similar view of a cross section along the line H in Fig. 1. In

Figs. 5, 6 and 7, a stopping piece forming an embodiment of this invention 1s shown in 'di'fierent views; the sectional view Fig. 7

Fig. 9 being a section along the line 99 in Fig. 8.

In the upper end of the bayonet handle a a slot Z) is provided which is usually of a crosslike form as shown in the drawing; however, a different form of slot may be used, if desired. In the illustrated example the slot is composed of a cylindrical portion and two lateral prismatic recesses 6 5 while the slot'opens through Z1 toward the adjacent backward face of the handle a. WVithin the top of the handle a hooked bolt 0 is slidably mounted,having at one end a cap cl screwed on, while the other end 0 projects into the recess 5 of the slot. The intermediate portion 0 of the doubly bent bolt is sunk into a groove in the side of the handle. The cap cl slides in a bore (Z which continues in a bore 6 of smaller diameter. Against the bottom of the bore 6 a spiral spring f is placed which bears, with the other end, against the cap d and keeps the locking bolt 0 in a position in which the portion 0 is flush with the side face of the fill up the slot 6 when the bayonet is not fixed on the gun. The stopping piece is shown in Figs. 5, 6, 7, and practically corresponds in cross section to the slot provided in the handle of the bayonet described above. There is a cylindrical part g fitting into the correspondingly shaped portion of the slot 6. The lateral projection g fits into the recess 5 While this projection g is carried down to nearly the whole length of the cylindrical part 9 the lateral projection 9 on the opposite side is made considerably shorter. Below the projection g a stop 2' is provided having an upper'rectangular face to engage with the hook 0 of the locking bolt 0. The back of the stop is inclined to gradually press back the locking hook 0 when the stopping piece 9 is being inserted into the slot 1) of the bayonet handle. The stopping piece has a further projection which fills up the slot opening 6 and is roughened on the outer face to afford the finger a better hold in withdrawing the stopping piece from the slot of the bayonet handle. In addition, a lug i may he provided to facilitate the removal of the stopper. The manner in which this novel stopping piece is applied can be readily inferred from the il strationsup the slot in the handle of the bayonet the stopping piece 9 is inserted with the cylindrica-l termination 9* down first. Then en: tirely pushed in, the top of the stoppmg piece is flush with the top of the handle. In withdrawing the stopping piece, the locking bolt 0 must first be moved out of the way of the stop by pressing down the cap a}. 7

A somewhat sim ler construction of the stopping piece is sown in Figs. 8 and 9. The cylindrical portion 51 is omitted and a plate I is permanently connected to the projection 9 This plate I: is bent, and the angularportion [c is made large enough to entirely and closely over-lie the top opening of" the cylindrical portion of the slot 6. This. modified construction is applied in the same manner as above described with reference to Figs. 13 to 7 a What I claim is I 1 The combination of a bayonet having a slot in the tea part of its handle and a spring-pressed locking bolt projecting into said slot, with stopping piece adapted to be inserted into said slot, said stopping piece being shaped to fill up said slot, and laterally "projecting shoulder on said stopping piece, adapted to engage said; locking bolt when said stopping piece is pushed home in said slot, substantially as described.

2. The combination of a bayonet having a slotin its handle which slot opens toward the top face and backward edge of said handle and is composed of a cylindrical portion, two lateral prismatic recesses, and a prismatic backward opening, and a doubly bent, spring-pressed locking bolt, projecting at one end into one of said lateral recesses and hearing, at itsothenend, cap that is sli'dably mounted within a bore of said handle, with a, stopping piece shaped to fill up the cylindrical portion, one lateral recess and the backwardopening. ofv said slotentirely and the second lateral recess of said' slot at the top portion, said stopping piece having a, laterally projecting shoulder taking into one lateral recess of; said slot, said shoulder being provided with; an in Gopies o f-this p atent' may he obtained for lvhen it is desired to. fill.

. 1. am f clined back face adapted to gradually press back said spring-pressed locking bolt while passing same, and being further provided with a straight front face adapted to engage said locking bolt, substantially as described.

3.. The combination of a bayonet havinga slot in its handle said slot being open toward the top face and backward edge of said handle and having two lateral recesses, and a doubly bent spring-pressed locking boltprojecting, at oneend, into one of said lateral recesses and bearing at its other end, a cap that is slidably mounted within a bore of said handle, with a stopping piece of cross-like section taking into said back face opening and both lateral recesses of said slot and havingin a lateral projection a shoulder toengage said locking bolt, said shoulder having an inclined front adapted to gradually depress said locking bolt when said stopping piece is being inserted into said slot and connected to said stopping piece a plate, closing said back face opening of said 'slot and having an end bent-in to closely overlie said top face opening of said slot, and 2;, lug on said plate adapted to facilitate withdrawal of said stopping piece,

substantially as" described. V

4. A'stopping piece consisting ofa cylindrical part, two low prismatic projections on opposite sides, one of which pro ections is considerably shorter than the opposite one, and a higher prismatic projection at the back, the latter projection having a roughened outer face and a lug thereupon adaptedto facilitate moving said stopping piece, i

and a laterally projecting shoulder below the shorter one of" said lateral projections, the front face of said shoulder being inclined whlle the back face of said shoulder falls. off rectangular, substantially as described. r

5. A stopping piece consisting of a cross shaped part having in one lateral projection a. shoulder with an inclined back, and a plate lengthwise connected to the'middle branch of said cross shaped part and overlying, with a bent-in. end, the top face of saidcross. shaped part, and a lug on said plate adapted to facilitate moving said stoppingpiece, substantially as described.
